I'm not sure that an 'official 6th quest' is a very good idea. What we need, are a set of new default quests that use open assets, not another baggage quest to support in a Zelda.pack.dat collection of sequentially numbered quests, and bizarre how-to-get-there rules and passphrases that might
need to change based on the .dat pack...
OTOH, Any contests to promote new quests that are similar in theme to 1st/2nd (difficulty, and gameplay) that use a collection of open assets are probably good ideas. After we have an official Open1st.qst / Open2nd.qst, we could then have contests to make new 3rd, 4th, and 5th entries for it, but I'm not sure that such things are warranted. (I'd rather give more freedom to the Quest Number than what we now have, by allowing the questmaker to pick a skip-to-name and other such nonsense, and to allow forwarding various elements from one quest, to the next in a series.)
These are the
audio assets thus far. I could certainly use some help with selection, and filling in the blanks. Feel free to have a contest for new music, graphics, or any other original content. That would indeed be helpful.
